Always keep hands and feet away from all moving parts during

operation. Moving parts can cut or crush body parts.

Always keep hands and feet away from all pinch points.

Do not touch parts that might be hot from operation. Allow parts

to cool before attempting to maintain, adjust, or service.

Stay alert, watch what you are doing, and use common sense

when operating the machine.

Do not overreach. Do not operate the machine while barefoot

or when wearing sandals or similar lightweight footwear. Wear

protective footwear that will protect your feet and improve

your footing on slippery surfaces. Keep proper footing and

balance at all times. This enables better control of the machine in

unexpected situations.

INSPECT YOUR MACHINE

Check your machine before starting it. Keep guards in place and

in working order. Make sure all nuts, bolts, etc., are securely

tightened.

never operate the machine when it is in need of repair or is in

poor mechanical condition. Replace damaged, missing, or failed

parts before using it. Check for fuel leaks. Keep the machine in

safe working condition.

Do not use the machine if the engine’s switch does not turn off

the engine when running. Any gasoline powered machine that

can’t be controlled with the engine switch is dangerous and must

be replaced.

Regularly check to see that keys and adjusting wrenches are

removed from the machine area before starting it. A wrench or

a key that is left attached to a rotating part of the machine may

result in personal injury.

Avoid accidental starting. be sure the engine’s switch is off before

transporting the machine or performing any maintenance or

service on the unit. Transporting or performing maintenance or

service on a machine with its switch on invites accidents.

If the machine should start to vibrate abnormally, stop the

engine (motor) and check immediately for the cause. Vibration is

generally a warning sign of trouble.

ENGINE SAFETY

This machine is equipped with an internal combustion engine. Do

not use on, or near, forest-covered or brush-covered land unless

the exhaust system is equipped with a spark arrester meeting

applicable local, state, or federal laws.

In the state of California, a spark arrester is required by law.

Other states have similar laws. A spark arrester, if used, must be

maintained in effective working order by the operator.

Never start or run the engine inside a closed area. The exhaust

fumes are dangerous, containing carbon monoxide, an odorless

and deadly gas. Operate this unit only in a well-ventilated

outdoor area.

Do not tamper with the engine in an effort to get it to run at

higher speeds. The maximum engine speed is preset by the

manufacturer and is within safety limits. See engine manual.

Keep a Class B fire extinguisher on hand when operating this

machine in dry areas as a precautionary measure.

FUEL SAFETY

Fuel is highly flammable, and its vapors can explode if ignited.

Take precautions when using to reduce the chance of serious

personal injury.

When refilling or draining the fuel tank, use an approved fuel

storage container while in a clean, well-ventilated outdoor area.

While adding fuel or operating the unit, do not smoke, and stay

away from sparks, open flames, or other sources of ignition near

the area of operation. Never fill the fuel tank indoors.

To avoid sparking or arcing, keep grounded conductive objects

– such as tools – away from exposed, live electrical parts and

connections. These events could ignite fumes or vapors.

Always stop the engine and allow it to cool before filling the fuel

tank. never remove the cap of the fuel tank or add fuel while the

engine is running or when the engine is hot. Do not operate the

machine with known leaks in the fuel system.

loosen the fuel tank cap slowly to relieve any pressure in the tank.

Never overfill the fuel tank. Because engine heat can cause fuel to

expand, never fill the tank to more than 1/2” below the bottom of

the filler neck. This will provide space for fuel expansion.

Replace all fuel tank and container caps securely and wipe up

spilled fuel. never operate the unit without the fuel cap securely

in place.

Avoid creating a source of ignition for spilled fuel. If fuel is spilled,

do not attempt to start the engine. Instead, move the machine

away from the area of spillage and avoid creating any source of

ignition until fuel vapors have dissipated.

When fuel is spilled on yourself or your clothes, wash your skin

and change clothes immediately.

Store fuel in containers specifically designed and approved for

fuel storage.

Store fuel in a cool, well-ventilated area, safely away from sparks,

open flames, or other sources of ignition.

never store fuel – or a machine with fuel in the tank – inside a

building where fumes may reach a spark, open flame, or any other

source of ignition (such as a water heater, furnace, or clothes

dryer). Allow the engine to cool before storing in any enclosure.

well away from the tines.

The tines remain stationary when the clutch is disengaged. If it

does not, have unit adjusted by a qualified repair personnel.

Always operate the machine from behind, never pass or stand in

front of the machine when the engine is running.

Always hold the unit with both hands when operating. Keep a firm

grip on the grips. Be aware that the machine may unexpectedly

bounce upward or jump forward if the tines should strike buried

obstacles such as large stones, roots, or stumps.

If the unit strikes a foreign object, stop the engine, disconnect the

spark plug, thoroughly inspect the machine for any damage, and

repair the damage before restarting and operating the machine.

Use extreme caution when in reverse or pulling the machine

towards you.

Do not overload the machine capacity by tilling too deep in a

single pass or at too fast a rate.

never operate the tiller at high transport speeds on hard or

slippery surfaces.

be careful when tilling in hard ground. The tines may catch in the

ground and propel the tiller forward. If this occurs, let go of the

handlebars and do not restrain the machine.

Use caution when tilling near fences, buildings and underground

utilities. Rotating tines can cause property damage or personal

injury.

Exercise extreme caution when operating on or crossing gravel

drives, walks, or roads. Stay alert for hidden hazards or traffic. Do

not carry passengers.

never leave the operating position when the engine is running.

Always stop the engine when tilling is delayed or when walking

from one tilling location to another.

Keep unit clean of vegetation and other materials. They

may become lodged between the tines. Stop the engine and

disconnect the spark plug before unclogging the tines.

To reduce exposure to vibration, limit the hours of operation

and take periodic breaks to minimize repetition and rest your

hands. Reduce the speed and force in which you do the repetitive

movement. Try to fill each day with jobs where operating hand-

held power equipment is not required.

OPERATION

1. Make sure the rear tine tiller is on a flat, level surface.

ADD OIL TO ENGINE

3. Using a funnel, add oil up to the FULL mark on the dipstick.

(See engine manual for oil capacity, oil recommendation, and

location of fill cap.)

The engine is shipped without oil. Do not start the engine before adding oil. Refer to your engine manual for the proper oil gauge to use.

Gasoline is highly flammable and explosive. You can be burned or seriously injured when handling fuel. Use extreme care when handling gasoline.

Fill the fuel tank outdoors, never indoors. Gasoline vapors can ignite if they collect inside an enclosure. Explosion can result.

IMPORTANT: DO NOT OVERFILL!

This equipment and/or its engine may include evaporative emissions control system components, required to meet EPA and/or CARB regulations, that will only function properly when the fuel tank has been filled to the recommended level. Overfilling may cause permanent damage to evaporative emissions control system components. Filling to the recommended level ensures a vapor gap required to allow for fuel expansion. Pay close attention while filling the fuel tank to ensure that the recommended fuel level inside the tank is not exceeded. Use a portable gasoline container with an appropriately sized dispensing spout when filling the tank. Do not use a funnel or other device that obstructs the view

of the tank filling process.

DO NOT OVERFILL. Check engine oil level daily and add as needed.

1. The engine must be off and allowed to cool at least two minutes

before adding fuel.

YT4565PM02 - 1704 Operation |

Do not stand directly behind tiller.

Rapid retraction of the starter cord (kickback) will pull your handand arm toward the engine faster than you can let go. Broken bones, fractures, bruises, or sprains could result.

4. Pull the recoil starter until the engine starts. Return the recoil

to the home position after each pull. Repeat the steps as

needed. Once engine has started, set the throttle to the FAST

position before you operate the unit.

TINE OPERATION - SHIFT LEVER

• Always release drive control bar before moving shift lever into

another position.

• Tine movement is achieved by moving shift lever to either the

counter rotating till position ( ) or the forward rotating

till position ( ) and engaging drive control bar.

FORWARD - WHEELS ONLY/TINES STOPPED

• Release drive control bar and move shift lever indicator to

“F” (forward) position. Engage drive control bar and tiller

will move forward.

REVERSE - WHEELS ONLY/TINES STOPPED

• Release the drive control bar.

• Move throttle control to “SLOW” position.

• Move shift lever indicator to “R” (reverse) position.

• Hold drive control bar against the handle and tiller will move backward.

If you find the shift lever difficult to move or find it hard to shift

gears, try one of the following:

• Briefly engage the drive control bar, and release, or

• Rock the tiller forward and backward using the handles

DEPTH STAKE

The depth stake (see Figure 7) can be raised or lowered to allow

you more versatile tilling and cultivating, or to more easily

transport your tiller.

DRAG BAR

The drag stake (see Figure 8) should be raised when tilling in the

counter rotating ( ) till position. The drag stake should be

lowered when tilling in the forward rotating ( ) till position.

TILLING

Tilling is digging in, turning over and breaking up garden soil and

prepare a seedbed for planting. Best tilling depth is 4” (100mm) to

6” (150mm). A tiller will also clear the soil of unwanted vegetation.

The decomposition of this vegetation matter enriches the soil.

Avoid tilling soil that is too dry as it will pulverize and produce a

dust that will not hold water. Water a few days before tilling. Also,

tilling soil that is too wet will produce unsatisfactory clods. Wait a

day or two after heavy rain for the soil to dry.

better growth will be obtained if an area is tilled properly and

used soon after tilling to preserve the moisture content.

Outer Side Shields

The type of soil and working conditions will determine the actual

setting of the tilling depth. In some soils, the desired depth is

reached first pass over garden. In other soils, the desired depth

is obtained by going over the garden two or three times. In later

case, the depth regulator rod should be lowered before each

succeeding pass over the garden. Passes should be made across

the length and width of the garden alternately. Do not try to dig

too deeply in the first pass. If the machine jumps or bucks, allow

the unit to move forward at a lightly faster rate.

If the tiller stops forward motion and tries to dig in one spot, rock

the handles from side to side to start it moving forward again.

Rocks which are turned up should be removed from the garden area.

• Move the depth stake pin lever to the unlock position (See Figure 5a, Illustration 2). Hold the depth stake limiter to pull the depth

stake up for increasing tilling depth. Place depth stake pin in the

hole of the depth stake to lock in position at desired depth.

YT4565PM02 - 1704 Operation |

Never use a “pressure washer” to clean your unit. Water can penetrate tight areas of the machine and its transmission case and cause damage to spindles, gears, bearings, or the engine. The use of pressure washers will result in shortened life and reduce serviceability.

GEARBOX

The gearbox was filled with lubricant to the proper level at the

factory. Unless there is evidence of leakage or service has been

performed on the gearbox, no additional lubricant should be

required.

GENERAL LUBRICATION

lightly lubricate all moving parts of the machine at the end of the

season or every 25 operating hours.

MAInTEnAnCE

Maintaining your YARDMAX rear tine tiller will ensure long life to

the machine and its components.

PREVENTIVE MAINTENANCE

1. Turn off the engine and disengage all command levers. The

engine must be cool.

2. Keep the engine’s throttle lever in its SlOW position and

remove the spark plug wire from the spark plug and secure.

3. Inspect the general condition of the rear tine tiller. Check

for loose screws, misalignment or binding of moving parts,

cracked or broken parts, and any other condition that may

affect its safe operation.

4. Use a soft brush, vacuum or compressed air to remove all

contaminants from the machine. Then use high quality light oil

to lubricate all moving parts.

5. Replace the spark plug wire.

ADJUSTING CLUTCH

If clutch becomes difficult to engage follow these

steps to adjust the cable tension.

1. loosen the jam nut by turning it counter clockwise with

8mm wrench while holding the adjustment nut in place

with 6mm wrench. (see Figure 10, Illustration 1)

2. Tighten (or loosen) the cable by turning the cable

adjustment nut clockwise (or counter clockwise) with

a 6mm wrench until you have reached your desired

tightness. (see Figure 10, Illustration 2)

3. Once you have reached your desired cable tightness,

tighten the jam nut by turning it clockwise until it is

tight. (see Figure 10 Illustration 3)

IDLE SPEED

Set the throttle control lever to the SlOW position to reduce

stress on the engine when work is not being performed. lowering

the engine speed will help extend the life of the engine, as well as

conserve fuel and reduce noise level.

STOP ENGINE

To stop the engine in an emergency, simply move the throttle

control lever on the handle to the stop position. Under normal

conditions, use the following procedure:

1. Move the throttle lever to the SlOW ( ) position.

2. let the engine idle for one or two minutes.

3. Move the throttle control lever on the handle past the slow

position to the OFF position.

4. Turn the fuel valve lever to the OFF ( ) position.

Do not move the choke control to CLOSE to stop the engine. Backfire or engine damage may occur.

Sudden stopping at a high speed under a heavy load is not recommended. Engine damage may result.

YT4565PM02 - 1704 Maintenance |

STORAGE

If the rear tine tiller will not be used for a period longer than 30

days, follow the steps below to prepare your unit for storage.

1. Drain the fuel tank completely. Stored fuel containing ethanol

or MTbE can start to go stale in 30 days. Stale fuel has high

gum content and can clog the carburetor and restrict fuel flow.

2. Start the engine and run until it stops. This helps prevent gum

deposits from forming inside the carburetor and possible

engine damage.

3. While the engine is still warm, drain the oil from the engine. Refill

with fresh oil of the grade recommended in the Engine Manual.

4. Use clean cloths to clean off the outside of the machine and to

keep the air vents free of obstructions.

Do not use strong detergents or petroleum based cleaners when cleaning plastic parts. Chemicals can damage plastics.

Do not store the machine with fuel in a non-ventilated area where fuel fumes may reach flame, sparks, pilot lights or any ignition sources.

5. Inspect for any loose or damaged parts. Repair or replace

damaged parts and tighten loose screws, nuts or bolts.

6. Store your unit on flat ground in a clean, dry building that has

good ventilation.
